Economic preflight for apps and agents that put money into Morpho vaults.

One call before every deposit.

Send the action your app is about to take. Flightproof reads the vault at a pinned block, runs your policy and answers allow, review or deny.

It checks exit liquidity, oracle freshness and deviation, depeg exposure, utilization and supply cap headroom.

Every answer carries a signed receipt of what was checked and why. Anyone can verify it offline.
